Title: Improvements in the manufacture of plugs for cigarettes
IPC: A24D3/02
Filed: 1948-12-03
Abstract: 656,764. Creped or corrugated paper. ZAUFAL, F., and CIGARETTE COMPONENTS, Ltd. Dec. 3, 1948, Nos. 31399 and 6017. [Class 96] [Also in Groups VI and XVI] In a method of making cigarette plugs wherein strips of creped or corrugated material with the corrugations disposed longitudinally thereof are fed to a plug-making machine, the strips are placed end-to-end in two or more layers so that the butt joints in adjacent layers are displaced from one another. A continuous laminated band 19 is formed by four sheets of transversely-creped or corrugated paper wound from reels 10-13 arranged so that the edges of the sheets are displaced to give the band stepped edges. Strips cut from the band are placed end-to-end so that the stepped edges of successive strips interlock to form a band with the corrugations running longitudinally thereof, which is fed to the plug-making machine or rereeled. The edges of the band 19 may be slit or it may be perforated by a roller 17 to prevent the strips remaining curved when the reel is unwound. In a modification the band 19 is formed from reels of untrimmed paper which are trimmed by pairs of knives positioned to produce the stepped edges. Absorbent material may be interleaved with the paper. Specifications 462,540, 462,585 and 623,939, [all in Group VI], are referred to.

Abstract: 390,101. Separating a single cylindrical body from a supply. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Nov. 7, 1932, No. 31412. Convention date, Nov. 20, 1931. [Class 142 (ii).] In a device for separating a single one from a supply of glass rods, wire-shaped electrodes, helically-wound wires or helices for electric light filaments or discharge tubes, two narrow jaws 1, 2 supporting the supply and so shaped that when they are moved together a single helix is gripped, the remainder being pressed upwards as shown by Fig. 2. The jaws are preferably inclined at different angles to a third surface, which may be the base of a member 4 housing the supply. The jaw 2 may be fixed and the jaw 1 be arranged to be moved first to the left by a lug 8 to allow at least one helix to penetrate the jaws, a slack spring 5 moving the jaw 1 to the right, when the member 4 returns to the right, whereby a single helix is gripped and the remaining ones are forced to ascend the incline 7 of the jaw 2, parts 4a, 4b on the member 4 forcing them further up the incline as the member 4 continues to move to the right. They are held in position by the descent of a light feeling finger 16 having a rubber tip &c. ; knife-shaped members 9 then move between the isolated helix and the remaining ones to complete the separation as shown in Fig. 3. In a modification, supplies of helices are carried between members 4, Fig. 4, interconnected by links 18 to form a chain passing over sprocket wheels and sliding over a plate 12, whereby a supply can be brought into position between the jaws 1, 2 arranged on a vertically moving table 10. Each member 4 has a lug for removing the jaw 1 periodically from the jaw 2 against spring action. After a supply has been exhausted, the table descends and the members 4 are displaced a distance S to bring a fresh supply into position.

Abstract: 1,086,813. Laminates. NATIONAL AERONAUTICS & SPACE ADMINISTRATION. July 26, 1965 [July 31, 1964], No. 31799/65. Heading B5N. A method of bonding a thermally protective plastics lamination to a metallic surface comprises heating a metallic surface and a layer of polytetrafluoroethylene under controlled conditions, fixedly positioning the polytetrafluoroethylene layer and the metallic surface relative to each other so as to provide a controlled gap distance therebetween, forcing a low viscosity thermosetting resin between the two layers to completely fill the gap distance therebetween, subjecting the resultant structure to controlled ambient pressure within a pressure chamber while maintaining the chamber temperature for a period of time sufficient to cure the resin and thereby bond the two surfaces and cooling the bonded structure to room temperature whilst maintaining it under pressure. The exemplified metal surface is a truncated metal alloy sleeve, the alloy being composed of thorium and magnesium, said sleeve serving as the metal antennµ structure for a re-entry vehicle, and having a plurality of circumferentially disposed radial projections on its exterior surface.

Title: Improvements in or relating to rubber surfaces and methods of preparing the same
IPC: B29C37/00
Filed: 1932-11-10
Abstract: Hardened surfaces which do not darken on exposure to light are obtained upon rubber articles such as golf-balls, tyres, heels, soles, overshoes, bathing-caps, and water-bottles, by incorporating into the rubber a colour stabilizing substance which consists of one or more proteins, or other amido compounds, oxides or hydroxides of alkaline earth metals, basic salts or organic salts of alkali and alkaline earth metals, and treating the rubber surface with a halide of an amphoteric element. Magnesium oxide, or oxychloride, calcium tartrate, a fatty acid salt of calcium or magnesium such as magnesium stearate, glue, gelatine, urea, acetanilide, the zinc salt of dithio-carbamic acid, are examples of substances used as colour stabilizer.  The rubber may be natural or synthetic rubber, balata, or gutta-percha, and may be compounded with the usual ingredients. Titanium dioxide, zinc oxide, lithopone, barium sulphate, and zinc sulphide, are suitable white pigments.  In examples, compositions for use as golf-ball covers contain resin free gutta-percha or balata, pale cr<\>zepe rubber, titanium dioxide, zinc oxide, magnesium oxide, urea, glue, sulphur, and an accelerator.  In the preparation of a golf-ball cover, the composition is moulded to shape with proper markings.  The formed ball is treated with an organic solution of an amphoteric halide such as tin tetrachloride in ethylene dichloride and ethyl acetate.  It is then washed with a solvent such as acetone or alcohol and allowed to dry.  The surface is hard and when polished has a low coefficient of friction.  It resists the darkening action of light to a high degree.  The composition may be applied to already formed articles or covers and the surface is then treated with amphoteric halide to produce a hard polishable surface. Specifications 320,427, [Class 70], and 384,911 are referred to.  The Specification as open to inspection under Sect. 91 refers also to the use of hydroxides of alkali metals as colour stabilizers. This subject-matter does not appear in the Specification as accepted.

Abstract: <PICT:0999534/C6-C7/1> An aluminium-lead alloy comprising 30-80% of aluminium and 20-70% of lead, together with a small amount (up to 5%) of lead oxide is produced by forming a powder mixture of lead monoxide and aluminium, heating between 800 DEG  and 1100 DEG F. in a reducing atmosphere to reduce substantially all the monoxide and compacting the mixture.  The aluminium may be replaced by conventional pre-alloyed powders containing such elements as magnesium, silicon, copper and nickel, compositions exemplified being aluminium-4% silicon, and aluminium-1% copper-1% nickel.  The reduced powder mixture may be compacted on to a backing strip to form a material suitable for bearings.  The aluminium or alloy powder should have a particle size ranging from less than 100 mesh to less than 325 mesh, while a suitable litharge has an average particle size of 5 microns.  In the embodiment shown in Fig. 1, backing strip 4 fed from coil 6 is provided with a layer 16 of lead-monoxide-aluminium powder mixture from hopper 10, the layer being smoothed by spreader 14.  The coated strip then enters heating chamber 18 where it encounters a reducing atmosphere at a temperature of 800 to 1100 DEG F., and then passes between compacting rolls, the lower of which has a peripheral speed equal to the speed of the strip, while the upper revolves at a slower rate, generally at a peripheral speed of one-tenth to one-fifth of the speed of the strip.  The compacted strip then passes through cooling chamber 32 where it is rapidly cooled to room temperature in an inert atmosphere, before being coiled at 36.
